Topographic Steering of the Upper Arctic Ocean Circulation by Deep Flows

Tellus: Series A, Dynamic Meteorology and Oceanography
Dynamically, the Arctic Ocean is characterised by the presence of closed f/H contours, where f is the Coriolis parameter and H the depth. On closed f/H contours, a net integrated surface wind stress can theoretically drive relatively strong near-bottom ...

Boundary Upwelling of Antarctic Bottom Water by Topographic Turbulence

AGU Advances, 2023
The lower cell of the meridional overturning circulation (MOC) is sourced by dense Antarctic Bottom Waters (AABWs), which form and sink around Antarctica and subsequently fill the abyssal ocean.

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

Droplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

A Method for Along-Track Interferometric Phase Elimination of Large Baseline Imaging Radar Altimeter

IEEE Access
The large baseline imaging radar altimeter (LB-IRA), deployed in a dual-satellite formation, enhances altimetric accuracy to sub-centimeter levels through the use of helical orbits to extend the interferometric baseline.

Topography constrains the climatic response of treeline migration in Taiwan's subalpine forests

Ecography, EarlyView.
Treelines are moving upslope, but the rates and drivers differ among different regions, globally. Many studies have examined the relationship between treeline movement and climate change, particularly rising temperature, while the role of topographical factors has received much less attention, despite the longstanding recognition of its importance.

Influence of Topography on the Large-Scale Ocean Circulation

Journal of Physical Oceanography, 1995
Abstract The influence of the bottom topography on the large-scale ocean circulation is discussed and illustrated with a simple model based on the ideal-fluid thermocline equations. The requirement that fluid remains in linear vorticity balance while conserving its density leads to a coupled problem, but one that can be reduced to a single ...

TOPEX/POSEIDON: The ocean topography experiment

Eos, Transactions American Geophysical Union, 1991
TOPEX/POSEIDON is a satellite mission that will use a radar altimeter system to measure sea level, which will reveal ocean topography and enable study of the circulation of the world's oceans. The measurement will also be useful for the study of ocean tides and marine geodesy and geophysics.

Hybrid Simulation–Machine Learning Surrogates for Coordinate‐Based Solar and Wind Energy Yield Assessment in Iraq: A Streamlit Decision‐Support Tool

Energy Science &Engineering, EarlyView.
This study integrates climatic simulations with machine learning to predict solar and wind energy across Iraq. Results show Random Forest excels for solar (R2 = 0.98) and neural networks for wind (R2 = 0.97), enabling a practical web tool for renewable energy planning. ABSTRACT Driven by the global shift away from fossil fuels, solar and wind resources

Combining T/P altimetric data with hydrographic data to estimate the mean dynamic topography of the North Atlantic and improve the geoid [PDF]

Annales Geophysicae, 1998
The mean dynamic topography of the surface of the North Atlantic is estimated using an inverse model of the ocean circulation constrained by hydrographic and altimetric observations.

Subspace Acceleration for Efficient Nonlinear Water Wave Simulation

International Journal for Numerical Methods in Fluids, EarlyView.
We introduce an exponentially weighted subspace acceleration technique to reduce GMRES iterations for solving the Poisson equation with time‐dependent coefficients in nonlinear, dispersive free‐surface flows governed by the incompressible Navier‐Stokes equations. The method significantly reduces memory requirements and computational complexity compared
